+Subject: ahci: Withdraw IGN_SERR_INTERNAL for SB800 SATA
+References: bnc#449873
+
+There is an issue in ATI SB600/SB700 SATA that PxSERR.E should not be
+set on some conditions, which will lead to many SATA ODD error messages.
+commit 55a61604cd1354e1783364e1c901034f2f474b7d is the workaround.
+Since SB800 fixed this HW issue, IGN_SERR_INTERNAL should be withdrawn
+for SB800.
